Question

Justin needs to make a illustrations for an art book. He had made 40%of the illudtrations. Make a bar model to show his progress. How many illustrations does he have

Answer 1

Justin has made 40% of the illustrations. First, calculate the number of illustrations Justin has made, by calculating the 40% of 80, just as follow:

(40/100)(80) = 32

that is, 40% is claculated by multiplying 40/100 by 80.

Then, justis has made 32 illustrations. To obtain the number of illustrations Justin has not made even, subtract the previous result to 80:

80 - 32 = 48

Then, Justin has not made 48 illustrations.

A bar model representing the previous situation is shown below:

where the red regios corresponds to the 32 illustrations made by Justin
